FAMILY, I— PEPCIDS. 59 



distinguished from A. frenatus by its higher body (3f to 1/4 in the total length) a serrated shoulder bone, a 

 smooth intramarginal edge to the preopercle, and a black spot at the base of the caudal fin, &c. 

 Habitat. — Mauritius, seas of India to the Malay Archipelago and beyond.

Length of head 3j, of caudal 2/9, height of body 3y in the total length. Eyes — diameter 2/7 of 

 length of head, nearly one diameter from end of snout, and 3/4 of a diameter apart. Jaws of equal length : the 

 maxilla reaches to below the last third of the eye. The outer edge of both the vertical and horizontal limbs of the 

 preopercle, and the shoulder bone serrated ; orbit entire. A fiat opercular spine. Teeth — villiform in jaws, vomer, 

 and palate. Fins — first dorsal spines rather strong, the fourth being the longest and equal to 2j in the height 

 of the body : soft dorsal much higher than the spinous, being equal to 3/5 of the height of the body, its upper 

 edge as well as the outer one of the anal slightly rounded : last dorsal and anal rays divided to their bases. 

 Pectoral as long as the head behind the middle of the eye : ventral slightly longer and reaching the anal : 

 caudal forked. Lateral-line — tubes arborescent, most distinctly so anteriorly. Free portion of tail rather 

 longer than it is high at its base. Colours — reddish-brown shot with gold, having a black band from the bases 

 of the first three dorsal spines to the axil of the pectoral fin : a second from the middle of the second dorsal to 

 the commencement of the anal fin : a small black spot near the end of the lateral-line : inner third of 

 ventral nearly black : a narrow dark band across the soft dorsal fin. 



This species is evidently closely allied to A. nigricans. 



The British Museum has received a specimen of this fish determined as above by Dr. Klunzinger. In 

 Cuv. and Val. it is stated to be brownish, with five longitudinal bands. Dr. Klunzinger considers it a variety 

 of bifasciatus, but the difference between the first dorsal fins in the two has led me to rather leave them as 

 distinct species. 



Habitat. — Red Sea and Madras, from whence the specimen figured (life size) was obtained.

Length of head 2/7, of caudal 1/5, height of body 2/7 of the total length. Eyes — diameter 2/5 of 

 length of head, 1/2 a diameter from end of snout, and also apart. The jaws equal in front : the maxilla reaches 

 to below the last third of the orbit. Outer edges only of the vertical and horizontal limbs of the preopercle 

 serrated : edges of orbit smooth : shoulder bone serrated. Teeth — villiform in jaws, vomer, and palate. Fins — 

 first and second dorsal spines short, the third equal to two-thirds the height of the body below it. Pectoral 

 equals the length of the head behind the middle of the eye : the ventral scarcely reaches so far as the anal : 

 caudal slightly notched. Lateral-line — tubes distinct, those in the first half of the body with lateral arborescent 

 branches. Colour — of a reddish-brown tinge, with a dark band from the upper edge of the orbit to the end of 

 the second dorsal and continued along the upper margin of the free portion of the tail and caudal fin : the 

 second passes below it to the base of the upper half of the tail, and then curves downwards : the third from the 

 head along the body below the lateral-line to the tail : the fourth along the upper part of the lower jaw through 

 the eye to the base of the pectoral fin. Sometimes intermediate, narrower and short dark bands are present 

 between those described. A black spot at the base of the tail. First dorsal fin black in its front half, a black 

 band along the centre of the second dorsal, a similar one along the base of the anal and continued to its last ray : 

 dorsal, caudal, and anal fins with darkish edges. 



Habitat. — From the Red Sea through those of India to the Malay Archipelago and beyond.

Length of head 3 J, of caudal 1/5, height of body 3f to 3| in the total length. Eyes — diameter 

 3j in the length of the head, 3/4 of a diameter from end of snout, and also apart. Lower jaw slightly the 

 longer : the width of the head equals half its length. The maxilla reaches to below the last third of the orbit. 

 Some serrations along the lower edge of the orbit : the shoulder entire. The outer ed?e of the vertical and
